Apple has unveiled the latest version of its Mac operating system, OS X 10.10 Yosemite. Undergoing a full redesign, Yosemite brings Apple’s desktop computers closer than ever to the iOS family of devices.

After months of anticipation and countless rumors, Tim Cook and his merry band of Apple fellows are about to take the stage at San Francisco’s Moscone West to reveal the latest offerings coming out of Cupertino. It’s time for the Worldwide Developers Conference.

We’ll be covering the WWDC action here all morning with news and analysis on everything like iOS 8, OS X 10.10, Healthbook and whatever other goodies the mothership has prepared. The keynote starts at 10 a.m. Pacific, so bookmark this page and keep it open for a tidal wave of Apple news and insights.

Hours before WWDC kicks off, a series of blurry leaked photos appear to show Apple’s next generation operating system, OS X 10.10 Yosemite, in action.

Two different sources of photos have been posted online: the first on the Reddit Mac community by a poster using a throwaway account, who claimed to have taken the photos himself at Apple’s headquarters in Cupertino. These images have since been deleted.

Assuming that the photos are genuine, they reveal several interesting changes in the look and feel of the OS — making it far closer resemble iOS. For instance, there is now a Control Center, along with a slightly rejigged Safari, with larger buttons for bookmarks and frequently visited sites, similar to the version of Safari found on the iPad.

When Jony Ive ripped Scott Forstall’s spine out (metaphorically speaking) and took over as the design head of iOS, he got rid of many gradients, shadows, and other elements that made the app look, at worst, skeuomorphic.

Sadly, though, Ive hasn’t had a chance yet to take the same approach to OS X. But everyone’s expecting OS X 10.10 to flatten OS X out, and Dribbble designer Danny Giebe has a gorgeous look at what the next version of Mac OS X — which he codenames ‘Syrah’ — would look like if Ive extended iOS’s design to the Mac.

In a new blogpost, New Zealand security consultant Aldo Cortesi notes that it took him less than one day to develop a proof of concept for the critical OS X SSL/TLS bug, known as “goto fail”.

By doing this Cortesi has confirmed in practice what people were already worried about in theory: that thanks to the bug — thought to be the result of a line of erroneous code — almost all encrypted traffic, including usernames, passwords, and even Apple app updates can potentially be captured.

One thing’s for sure: once you have iOS 7 installed, OS X Mavericks sticks out like a sore thumb. iOS 7 is where Apple’s software design is headed, and OS X Mavericks is what Apple’s software design aesthetic is fleeing from.

Clearly, OS X Mavericks was left alone this year because Apple couldn’t concentrate on two design overhauls at once. Instead, Ive & Co. simply satisfied themselves with stripping out some of OS X’s more Forstallian flourishes, like the Corinthian leather and gray linen textures.

But what about next year? What would OS X 10.10 look like if brought in line with the design of iOS 7? DeviantArt user Ohsneezeme‘s concept, while not perfect — he hasn’t touched the icons or the dock — is a strong guess.
